HENRY SENGER, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-THIRD TO THOMAS H.MUSGRAVE, OF SAME PLACE.

GYMNASTIC STRlKING-BAG.

SPECIFIGATIOfi forming part of Letters Patent No. 475,252, dated May 17,1892.

Application filed June 11, 1891. Serial No. 395,857. (No model.)

.To all whom it may concern: N

Be it known that I, HENRY SENGER, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in Gymnasium Striking-Bags, of whichthe following is a specification.

This invention relates to an improvement in striking-bags for gymnasiumuses, and the object in view is toproduce a lighter and more durable andserviceable bag than has heretofore been known.

To this end the invention consists in the features of noveltyhereinafter pointed out, and specified in the claim.

The invention is illustrated in the accompanying drawings, in whichFigure 1 represents a perspective View of one of the hemisphericalsections of which the bag-cover is composed. Fig.2 represents a top viewwith the top loop by which the I bag is suspended removed and the flapwhich covers the lacing turned back. Fig. 3 represents a similar view,in which the flap is shown secured down over the lacing. Fig. 4 is aside view of the bag complete ready to be suspended, a portion of thecovering being broken away to show the ball in the covering; and Fig. 5is a side View of the bag suspended ready for use.

The bag proper B consists of rubber, as usual, and has a tube a, bywhich it is filled with air or blown up. I make the cover-. ing for thisrubber bag of two semi-spherical sections or halves A of leather sewedtogether by a single seam b, as represented. These semi-sphericalsections are made by stretching the leather over a suitable block orformer to give them the proper shape, and when they are sewed togetherthey form a perfect sphere.

A bag made as above described has the advantage of being lighter andmore durable than when made with a greater number of seams, for there isless liability of rupture, and consequently very few repairs necessary.Moreover, there are not so many hard seams to encounter in the use ofthe bag, and it will retain its spherical shape better than any bag madewith a greater number of seams.

In sewing the two half-spherical sections together a slit or opening 0is left for the introduction of the rubber bag and through which thetube a projects. on either side of this slit eyelets d are fastened inthe'leather and the slit is closed by lacing 6, passed through saideyelets. The eyelets and lacing are covered and concealed by a leatherflap f, which is secured at one end tothe bag by stitching g'and has ahole a, through which the filling-tube a extends. The ends of the lacingare passed through small holes 6 in the opposite end of the flap andthen tied over the same, as shown at 71., thus fastening down the saidflap. The flap is further secured by gluing or cementing its free end fto the bag. A loop 4. is secured by rivets t" to the top of the bag andcovers the tube a. By means of this loop the bag is hung or suspended. Ialso attach a loop j to the bottom of the bag, to which may be connecteda rope or strap (shown in dotted lines in Fig. 5) running to the floorto hold the bag stationary if it is desired to use it in this-way.

The bottom attachment in striking-bags heretofore has been as follows: ahole through the bottom of the bag bound with leather, a washer ofleather inside the bag, and a strap or cord extending through the holeand connected with the washer. This construction is objectionablebecause it adds to the weight of the ball and the strap or cord cannotbe detached. By my simple loop on the eXtev rior the weight of the bagis not perceptibly increased and a strap can be readily attached anddetached and the bag quickly converted from a swinging to a stationarybag.

I may also make the bag oval and of two parts with a single seam.

The bags may be made of any size desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A gymnasium striking-bag having a cover made in two hemispherical partswith a single connecting-seam extending in a straight line around itscircumference, and a slit or opening closed by lacing and having a flapsecured at one end to the said cover and concealing said lacing, theends of the latter extending through the flap and tied over the same.

In testimony whereof I aflix my signature in the presence of twowitnesses.

HENRY SENGER.
